4 Claims. 1

This invention relates to the mounting of globes, such, for example, asterrestrial and celestial globes but more particularly to the mountingof relatively large globes which are made up of hemispherical sections.

An object is to produce a new and improved mounting for a large globemade up of hemispherical sections by which the sections are efiicientlyconnected together in proper relation to each other, thereby to militateagainst the sections of the globe shifting laterally with respect toeach other.

Another object is to produce a relatively large illuminated globe madeup of hemispherical sections and to improve the means whereby thesections are connected together and by which the lamp is installedinside of the globe to efiect the desired illumination.

Another object is to improve the structure and mounting of illuminatedglobes of the type made up of hemispherical sections which arerelatively large and ordinarily diflicult to maintain in proper relationto each other and to facilitate the mounting of the lamp or illuminatingmeans inside the globe, a difiicult problem where the globe is large andspace for the illuminating means small and restricted.

Other objects and advantages of the invention will hereinafter appear,and for purposes of illustration but not of limitation, embodiments ofthe invention are shown in the accompanying drawings, in which Figure 1is a side elevation of an illuminated globe and its mounting, partsbeing broken away for purposes of clarity;

Figure 2 is an enlarged fragmentary vertical sectional View of themounting and illuminating means for the globe hown in Figure 1;

Figure 3 is a transverse sectional view on the line 3-3 of Figure 1;

Figure 4 is a transverse sectional view on the line 4-4 of Figure 2;

Figure 5 is an enlarged fragmentary view showing the end portion of oneof the radial arms and illustrating the pin and socket connectionbetween the end of the arm and adjacent globe ections; and

Figure 6 is an enlarged vertical fragmentary section of a globe showingan alternate form of mounting and globe illuminating means.

The illustrated embodiment of the invention comprises a globe made up ofa pair of hemispherical sections I0 and l l of glass or other suitabletranslucent material. The globe i carried by a metallic ring I2 which issuitably secured to a pedestal or support [3. The diametrically opposedportions of the globe sections are apertures l4 and [5 in the globesections l0 and II respectively. In the aperture 15 i a bushing i6 whichhas internal screw threads. The bushing has an external flange I! whichbears against the outer surface of the globe section II and isadhesively secured thereto.

Formed in the mounting ring I2 is a socket [8 to receive a pin [9 rigidwith the outer end of an externally screw-threaded member 20 which is inthreaded engagement with the bushing I6.

Fitting in the aperture [4 of the globe section It is a bushing 2!, aportion of which extends inside the globe section and on the outer endis an annular flange 22 which is adhesively connected to the outer sideof the globe section it].

Connecting the bushings I6 and 2| is a wire cage 23 which consists of anannular series of equi-distantly spaced wires the lower ends of whichare secured as by soldering to the outer side of that portion of thebushing 2| which projects inside the globe section lil. The oppositeends of the wires are secured as by soldering to a ring 24 which engagesthe screw-threaded member 20 and is dapted to abut against the innerface of the bushing I6 on the inside of the globe section I I. Thecentral portion of the wires which make up the cage 23 are outwardlybellied by an annular wire ring 25 to which the several arms aresoldered. Radiating from the Wire ring 25 is an amiular series of wirearms 26 which are equidistantly spaced from each other and are securedas by soldering at their inner ends to the ring 25. The outer ends ofthe arms 26 are flattened as indicated at 2'! and extending through eachfiattened portion is a pin 28, portions of which project above and belowthe flattened end 2! to extend into sockets in the abutting edge wallsof the globe sections it) and Il. Thisprovides a positive connectionbetween the adjacent globe sections and militates against one sectionshifting out of proper register with each other. It will thus be seenthat the globe sections even though of relatively large ize, are securedtogether and relative axial and lateral movement is positivelyprevented.

Arranged within the wire cage 23 is an elongate tube 29 of glass orother suitable transparent material. Secured to the upper end of thetube 29 is a flanged plug 30 having an outwardly extending rigid pin 3|which fits into a socket 32 in the inner end of the threaded memberZfl.The tube 29 is inserted through the aperture [4 of the globe section it)and to enable it. to be inserted so that the pin 3! fits into the socket32, an annular series of guide wires 33 are'provided. The upper end ofeach wire 33 is soldered to the under face of the ring 24. The lowerportions of the guide wires 33 bow inwardly and thence flare outwardlyto the wire cage 23 to which the ends of the individual wires are hookedas indicated at 34. Thus the several wires 33 assist materially inguiding the upper end of the tube 29 and enabling the pin 3| to beinserted readily into the socket 32. It will be manifest that in absenceof such guiding means and in view of the large size of the globe,considerable difliculty would be encountered in mounting the upper endof the tube in the desired manner.

Fitting the opposite end of the tube 29 is a flanged plug 35, the flangebeing on the outside of the tube and being disposed within the bushing2|. Arranged adjacent the inner end of each of the plugs 30 is astarter: disc 36 which is urged axially of the tube by springs 31thereby to retain a fluorescent tube or lamp 38 therebetween, a lead 39supplying current to the upper starter disc.

The flange of the plug rests against a disclike head 40 of a post 4|which has a reduced lower end fitting a transverse recess 42 in theadjacent portion of the supporting ring l2. A screw 43 extends through ahole in the ring l2 and threadedly engages the reduced portion of thepost 41 to retain the parts in position.

The plug 35 may constitute a switch of any suitable character, a pullchain 44 being operatively connected to the switch and extending througha passage formed in the plug and post 41.

In the form of the invention shown in Figure 6, the opposite ends of.the screw-threaded member 20 are socketed and in the upper socketextends a pin I9 carried by a plug 45 which fits into a cavity in thesupporting ring I2, a screw 46 retaining the plug 45 in place.

In this form of the invention, the bowed guide wires 33 have their lowerends outwardly flared but out of engagement with the wire cage. In thisform the plug 30' has a lamp receiving socket 41 to receive an elongateelectric lamp 48. The

plug 30 is connected by a lead 49 to the lower,

plug 35 which is likewise provided with a lamp receiving socket 50 toreceive the elongate lamp 5!. Thus it will be apparent that upon actuat--ing the switch (not shown), arranged within the plug 35' both the lamps48 and 5! are lighted.

in details of construction, arrangement and operation may be effectedwithout departing from the spirit of the invention especially as definedin the appended claims.

What I claim is:

1. A globe mounting comprising an external support, a pair ofsemi-spherical translucent globe sections in abutting relation, eachhaving an aperture diametrically opposed to each other when the sectionsare assembled, an internally threaded bushing in one aperture andconnected to the respective globe section, a member in threadedengagement with said bushing and having a head at the outer endconnected for turning movement with respect to said support, a socketedinner end portion on said member projecting inside of the respectiveglobe section, a bushing fitting the aperture of the other globe sectionhaving a flange connected to said section on the outside and with aportion projecting inside said section, a ring threadedl'y engaging theoutside of said socket end portion, a wire cage fixed at one end to saidprojecting bushing .portion and at the opposite end to said ring, an
